Genitalia. Female segment reduced, less than two-thirds as wide 

 as the penultimate, consisting of an obtusely triangular plate with the 

 apex produced into a strap-like tooth as long as the segment. A pair of 

 broad plates arising under this segment cover the base of the pygofers 

 and a pair of heavy folds occupy the corners. Male valve rounding, 

 plates narrow, scarcely as wide as the valve, concavely narrowing to the 

 blunt points, two and one-half times as long as the valve, not quite as 

 long as the compressed pygofers. 



Described from seven specimens from Orizaba, December 

 (H. S. and F. D. G.); Chilpancingo, Mex., June, (H. H. S.) ; 

 and one female from Vienna Museum labeled mexicana det. 

 Sign. 



Phlepsius (Texananus) excultus Uhl. (Fig. 8a, b and c). 



This strikingly marked species resembles eugeneus in 

 structure and decorus in markings but the fulvous dorsum and 

 commisural line will at once distinguish it. It ranges through 

 the southern United States and a single specimen is at hand 

 from Puentad, Ixtla, Mexico, July (C. C. Deam). 



Phlepsius (Texananus) hosanus n. sp. (Fig. 9a and b). 



Fomi and general appearance of decorus O. & B. slightly smaller 

 and with a definite concave light line between the ocelli. Length 6 mm., 

 width 2}4 mm. 



Vertex transversely convex, slightly sloping to the narrow margin, 

 one-fifth longer on middle than against eye, twice wider than long. 

 Front moderately broad above, wedge shaped, distinctly longer than 

 wide. Pronotum but little wider than across the eyes. Elytra longer 

 and more flaring than in decorus. 



Color. Vertex brownish fuscous; a spot at apex, the line between 

 ocelli and the base ivory white. Pronotum with tawny markings on the 

 anterior third. Scutellum tawny with light and black spots. Elytra 

 ivory white, with fuscous irrorations coalescing into irregular spots 

 omitting the inner margin back to apex of clavus. This ivory margin is 

 narrow next the scutellum and is crossed by the inner claval nervure. 

 It widens out on middle of clavus and again before apex and usually 

 bears one or more black spots in each expansion. 



Genitalia. Female segment short, posterior margin nearly truncate 

 with four triangular teeth on the middle third, the outer pair the larger. 



Described from two females, from Orizaba, Dec, (H. S. 

 and F. D. G.); and Tepetlapa Guerrero, Mex., Oct. (H. H. S.). 

 The broad, stout form and the dark color within the median 

 ivory spots render this an easily recognized form.
